Device Health and Status

Use the Device Health and Status branch to view the current health and status messages for the E1 NTU. Table 4-2lists these messages in priority order.

To display device health and status,

1. From the top-level menu screen, select Stat.

E1 HDSL NTU

Stat Test Cnfig

F1 F2 F3

2. From the Status screen, select DevHS.

Status:
HDSL	DevHS STest
F1	F2	F3

Alarm/status messages appear on Line 2 of the LCD in priority order (highest to lowest). The E1 NTU is polled for current status every ten seconds. If the status has changed from the last poll, the Health and Status screen is updated and the highest priority message is displayed.

3.Use the scroll keys, if necessary, to scroll additional device health and status messages onto the LCD.

Message	Description
LOS on Loop1	A Loss Of Signal condition (6 consecutive synchronization word mismatches) has been detected
	on loop 1 of the network interface. The condition is cleared when a signal match occurs.
LOS on Loop2	A Loss Of Signal condition has been detected on loop 2 of the network interface. The condition is
	cleared when a signal match occurs.
LOS at DTE	A Loss Of Signal condition (175 consecutive zeros) has been detected on the G.703 DTE interface.
	The condition is cleared when the density of ones to zeros received is 12.5%.
OOF at Net	An Out Of Frame condition (3 consecutive errored frame alignment events or, in CRC4 mode, a
	lack of multiframe alignment) has been detected on the network interface. The condition is cleared
	when a reframe occurs.
OOF at DTE	An Out Of Frame condition has been detected on the G.703 DTE interface. The condition is
	cleared when a reframe occurs.
AIS at Net	An Alarm Indication Signal (unframed all ones signal) is being received by the network interface.
AIS at DTE	An Alarm Indication Signal is being received by the G.703 DTE interface.
EER at Net	An Excessive Error Rate condition has been detected on the network interface (the bit error rate
	is 10-3or greater for 4 to 5 seconds). The condition is cleared when the error rate falls below the
	threshold value (10-4) for 5 seconds.
